John Silas "Jack" Reed (October 22, 1887 – October 17, 1920) was an American journalist, poet, and socialist activist, best remembered for his first-hand account of the Bolshevik Revolution, Ten Days that Shook the World.
In the autumn of 1913 John Reed was sent to Mexico by the Metropolitan Magazine to report the Mexican Revolution. He shared the perils of Pancho Villa's army for four months, present with Villa's Constitutional (Constitutionalist) Army (whose "Primer Jefe" was Venustiano Carranza) when it defeated Federal forces at Torreón, opening the way for its advance on Mexico City. Reed's time with the Villistas resulted in a series of outstanding magazine articles that brought Reed a national reputation as a war correspondent. Reed deeply sympathized with the plight of the peons and vehemently opposed American intervention, which came shortly after he left. Reed adored Villa, while Carranza left him cold. Reed's Mexican reports were later republished in book form as Insurgent Mexico, which appeared in 1914.
